CHAPTER 5: SYNCHRONIZATION,
BACKUP AND MISC CONTROLS
5.0 SMPTE
5.0A SMPTE Formats
The SMPTE button may be pressed repeatedly to cycle through the
various types of SMPTE that can be generated and/or synchronized
to, and used for locating when SMPTE Display Type is selected. The
choices are: 24 fps (frames per second), 25 fps, 29.97 fps, 29.97 fps Drop
Frame, 30 fps, and 30 fps Drop Frame.
The LED(s) associated with the currently selected SMPTE format will
be lit solid. When the BRC is set to synchronize to an external SMPTE
source, the SMPTE format of the source will automatically be
detected. It is not possible to receive one SMPTE format while
outputting another SMPTE format; therefore, when receiving SMPTE
timecode, the SMPTE format LED will change automatically (if
necessary) to correspond with the incoming format, so that both
SMPTE input and output formats will be the same.
Note: In the case of 29.97 and 30 fps, you will have to specify which
rate is currently being received, since they are too similar for the
BRC to distinguish a difference between them, due to possible
source speed variations. If the SMPTE input is encoded with drop
frame, the BRC will assume that 29.97 Drop Frame was intended,
unless you specify otherwise.
5.0B SMPTE Start Offset
The SMPTE START OFFSET button is used to set a SMPTE start time
offset for the current song. This is the SMPTE position that is to be
associated with the song start position (see section 4.6A). If SMPTE is
selected as the type of sync information to be generated (see section
5.0D), then this offset will be reflected in the BRC’s SMPTE code
output.
To set the SMPTE start offset:
1. Press the SMPTE START OFFSET button;
The display will show:
